20080256773 | Split Fan Wheel and Split Shroud Assemblies and Methods of Manufacturing and Assembling the Same - Devices and systems for transporting a material suspended in a fluid, e.g., pulverized coal, that can be assembled about a rotary element are disclosed. The devices and systems comprise a first portion or half of a fan wheel assembly, a second portion or half of a fan wheel assembly, and a plurality of splice plates for connecting the first portion of the fan wheel assembly to the second portion of the fan wheel assembly about the rotary element. Methods of manufacturing and assembling the sectionalized devices and systems are also provided. | 10-23-2008 |
20080272217 | SWING HAMMER FOR PARTICULATE SIZE REDUCTION SYSTEM - The invention provides a particulate size reduction system including a grinding chamber, a center shaft defining an axis of rotation and configured for rotational motion within the grinding chamber, a wheel assembly mounted on the center shaft and at least one swing hammer mounted on the wheel assembly. The at least one swing hammer preferably includes a base portion having a first end having a mounting portion for attachment to a wheel assembly of a material treatment system, a second end, an inboard portion proximate the mounting and an outboard portion proximate the second end. The swing hammer also preferably includes a wear pad disposed on the base portion. The wear pad preferably substantially covers a face of the base portion. The wear pad preferably extends from a point proximate the second end of the base portion toward the first end of the base portion to a location proximate the mount. | 11-06-2008 |
20090250538 | Swing hammer for particulate size reduction system - The invention provides a particulate size reduction system including a grinding chamber, a center shaft defining an axis of rotation and configured for rotational motion within the grinding chamber, a wheel assembly mounted on the center shaft and at least one swing hammer mounted on the wheel assembly. The at least one swing hammer preferably includes a base portion having a first end having a mounting portion for attachment to a wheel assembly of a material treatment system, a second end, an inboard portion proximate the mounting and an outboard portion proximate the second end. The swing hammer also preferably includes a wear pad disposed on the base portion that preferably includes an interrupted surface to improve wear resistance of the swing hammer. | 10-08-2009 |
20090272303 | Anti-roping Device for Pulverized Coal Burners - An orifice plate for improving particle distribution within a coal piping system includes a plate body defining a central orifice therethrough bounded by an inner periphery of the plate body. The plate body is configured and adapted to be affixed between end flanges of adjacent pipes in a coal piping system so as to generally align the central orifice with an internal flow passage through the coal piping system. Flow disruption features are defined in the inner periphery of the plate body. The flow disruption features are configured and adapted to disrupt a flow of air and particles flowing through the central orifice to provide a more uniform distribution of particles downstream of the plate body than upstream. | 11-05-2009 |
20100044282 | DEFLECTOR DEVICE FOR COAL PIPING SYSTEMS - A deflector device for improving particle distribution within a coal piping system includes a base defining an outer circumference. The base is configured to be mounted inside a pipe such that the base extends partially around the inner circumference of the pipe with the circumferences of the pipe and base being substantially aligned concentrically. A deflector extends radially inward from the base. The deflector is configured to direct a concentrated flow of coal particles toward the center of the pipe. | 02-25-2010 |
20120174400 | SPLIT FAN WHEEL AND SPLIT SHROUD ASSEMBLIES AND METHODS OF MANUFACTURING AND ASSEMBLYING THE SAME - Devices and systems for transporting a material suspended in a fluid, e.g., pulverized coal, that can be assembled about a rotary element are disclosed.
